CYLINDER-COCK.

SPECIFICATION forming part of Letters Patent No.350,276, dated October 5, 1886.

Application tiled April 6, 1886. Serial No. 197,054. (No model.)

To all whom it may concern.-

Beit known that I, WILLIAM SToErEL, of McHenry, in the county of McHenry and State of Illinois, have invented a new and Improved Cylinder-Cock Attachment, of which the following is a full, clear, and exact description.

My invention relates to the construction of an apparatus applicable for use in connection with the steam-cylinders of a locomotive or other form of engine, the object of the invention being to provide an attachment whereby the water of condensation may be automatically discharged from the cylinder at each stroke ofthe piston, the apparatus, however, being so arranged that it may be set to open both valves at once or to close both valves at once; and the invention consists of certain novel constructions and combinations ot' parts to be hereinafter described, and specifically pointed out in the claims.

Reference is to be had to the accompanying drawings, forming a part of this specification, in which similar gnres of reference indicate corresponding parts in all the figures.

Figure l is a side View of a portion of a cylinder provided with my improved attachment, the valve-chambers being broken away and shown in central sect-ion to disclose the construction of the parts. Fig. 2 is aplan View of the attachment, the view being taken on line a' a: ot' Fig. 1, certain portions otl the attachment being shown in section. Fig. 3 is a detail view in partial section,illustrating the construction of one of the valve-plugs and its connection, and Fig. 4 is a sectional view taken on line y y of Fig. 2.

In the drawings above referred to, A represents the cylinder of a locomotive-engine, be-

Lneath which there are arranged two valvechambers, B B, connection between the cylinder and the valve-chambers being established by means of tubes a a. These valve-chambers B B are each provided with inwardly-extending brackets b b, in which there is loosely mounted a rod, c, the rear end of which. is pivotally connected to the lower end of a lever, C, the upper end oi' said lever being provided with a connecting-rod, d,which extends backward to a position within reach of the engineer, the lever C being fulcrumed ate, as indicated. The rod d is provided with three notches, arranged as indicated, and designated by the numerals l 2 3, and the parts are so arranged that each of these notches may be brought into engagementwithastop, t, located plug-valves D there are formed apertures n a,

through which the water of condensation entering the valve-chambers will be discharged, 6 5' the valves D being arranged so as to ttloosely within the chamber. The extending ends of the valvc-stemsf are held within apertures g, that are formed in the forward ends of cylinders G, said cylinders being adjnstably con- 7o nected to rodsNN, said rods being in turn pivotally connected to a rocker, I?, that is carried by the arm H, said arm being clamped to the rod c by means of a plate, h, that is held to the arm II by means of a bolt or set-screw, Z, this construction being best shown in Fig. 4, where it will be seen that the arm H and plate hare formed with two or more sets of recesses, so that the position of the rocker P may be adjustedv either toward or from the rod c, as 8o the circumstances of the case require. The valve-stems j" are held within the socket g by means of bolts or set-'screws m, which it within apertures formed in the valve-stems and pass through the cylinders G, the apertures in the valve-stems being enlarged in order to permit of a slight play, so that the valves may be properlyseated in operation.. Connection between the cylinders G and the rods N N is established. by means of the clamping-yoke I, a set-screw, o, and a wedge, L, interposed between the rod and the cylinder, as best shown in Fig. 3, the inner face of the yoke opposite the wedge being inclined to correspond with the inclined. face of the wedge, the idea being I to give an appropriate direction to the rod N or N', said rods being set at a slight angle, as indicated in Fig. 2.

In operation we will suppose the steam to have entered in front ofthe piston within the Ioo cylinder A, and this steam would have entered the forward valve-chamber through its tube c,

and would have forced the valve B of the said forward valve-chamber against its seat, and as the valve of the forward valve-chamber moved to its scat the rocker P would have been thrown in the direction oi.' the arrow shown in Fig. 1, and in so moving would have carried thc rod N in the direction o1' the arrow shown in connection therewitlntlius moving the valve of the rear valvc-ehamber away from its seat to open a free passage Vl'or the water of condensation that was behind the piston in the cylinder A, the opening a in the rear valvechambcr at this time allowing for the passage of the water. Vhcn steam enters behind the piston in the cylinder A, the valve-plug D of the rear valvechamber will in turn be forced against its seat, thus moving the connecting parts in a direction opposite to that above de scribed, so as to carry the valve D ol the forward valve-chamber away from its seat, so as to allow l'or the outward passage ofthe water of condensation from in front of the cylinder A. ll' they engineer dcsiresto close both of the valvechambers at the same time, he can do so by moving the rod d backward so that the stop with which it engages will enter the rst notch formed in said bar or rod, l'or it will be seen that the movement of the rod cljust described will move the rod c forward in the direction oi' the arrow shown in connection therewith in Fig. l, and this movement will carry both ol the valve-plugs to their seat. On the other hand, if the engineer desires to open both ol' the valve-cylinders at the saine time, he can move the rod Z so that the stop will be in engagement with the third notch in the rod,which movement of the rod d will carry both valve-plugs over from their seats.

Having thus fully described my invention, what I claim as new, and desire to secure by Letters Patent, is-

1. The combination, with two valve-chambers and their valve-plugs, of a rocker carried by an arm that is secured to a sliding rod,and connections between the rocker and valve stems, substantially as described.

2. The combination, with two valvcchalnbers and their valve-plugs, said plugs being provided with stems, cylinders (Lin which the valve-stems are seated, clamps Il', connectingrods N N', a rocker, I), an arm, ll, a sliding rod, c, a levcr, C, and a connecting rod, (l, substantially as described.

8. The combination, with two valve-chant bers and their valve-plugs, of cylinders (l, `in which the stems ot' the val ves arc seated, clamps l, rods N N', a rocker, P, carried by an arm, H, arod, c, to which the arm His clamped, a lever, C, a connecting-rod, (l, formed with notches, and a stop, T, substantially as described.

4. The combinz'itiomwith a cylinder, ol` two valve-chambers in connection with they ends ol' said cylinder,and provided with outlets, plugs closing the said outlets and having outwardlyextendingstems, alongitudinally-movable rod, a rocker carried by said rod, and connections between the ends of' said rocker and the plug stems, as set iforth.
